Pasta noodles fuel the fires in these factories. OSF International operates more than 40 Old Spaghetti Factory restaurants in 15 states, primarily in California, Oregon, and Washington. The casual-dining spots offer a variety of Italian-style dishes, including lasagna, ravioli, tortellini, and, of course, spaghetti served with several kinds of sauces. Other menu items include sandwiches and a selection of daily lunch specials. Greek immigrant Guss Dussin opened the first Old Spaghetti Factory in Portland, Oregon, in 1969; his family continues to control the company.
